Horticultural LED lighting

Light provides energy for plant growth



Plant lighting Light, which provides energy for plant growth

With the development and maturity of artificial intelligence and plant lighting technology, LED horticultural lighting sources have a tendency to gradually replace traditional plant lighting sources represented by sodium lamps because of its low energy consumption, high luminous efficiency, and long service life,which has developed into a hot industry chain in recent years. Many domestic and foreign companies have also deployed plant lighting fields, and their application market has gradually become a new direction for the development of the LED industry, such as: plant supplement light and full replacement growth lights using in landscape lighting, aquarium lights and family or plant factory type.Shenzhen Refond Optoelectronics has always adhered to the policy of leading technology, and is constantly committed to the research and development of new hot spots, new technologies and new products. The latest research and development of LED plant lighting products can effectively meet the needs of the current plant lighting market. Recently, a variety of LED plant packaging products have been launched, including 2835, 3030, etc., covering the main wavelength bands of plant lighting such as 450nm, 660nm, 730nm, and full spectrum series or customized spectrum products.Let's take you to learn about LED plant lighting, Refond lighting products and applications.


What is LED plant lighting

Plant growth mechanism:


Plant growth mainly uses light energy, carbon dioxide and water to synthesize organic matter such as chlorophyll; the light form (spectral characteristics, irradiation conditions and intensity, etc.) is used to control stem growth, flower formation, and seed germination.

From the plant photosynthesis spectrum, it can be seen that plant photosynthetic pigments (chlorophyll a, chlorophyll b, carotene, etc.) have strong photosynthesis at 440-470nm and 620-660nm light waves, especially there are photosynthetic absorption peaks near 450 and 660nm. At the same time, studies have found that 730nm can promote the elongation of plant stems, increase leaf length and leaf width, and control the entire process of plants from germination, vegetative growth and flowering. Therefore, the current mainstream wavelength bands of LED plant lighting are WLP 450nm, 660nm, 730nm, which must meet the entire growth cycle of plants, covering plant growth PAR 365-780nm, and also cover supplementary band products such as 365nm, 410nm, 530nm, 590nm, 620nm, 640nm. However, the spectrum of pure single color light products is narrow, which cannot meet the growth needs of plants. It needs to be matched with a specific spectrum according to the growth cycle and characteristics of various types of plants, and meet a certain intensity of irradiation distribution. It is commonly called "light food" for plant growth.

LED horticultural lighting packaging device products are mainly divided into PAR 365-780nm monochromatic light devices, chip and phosphor color light or full-spectrum devices, and RGB, RGBWW and other dimming combination devices.


The difference between horticultural lighting and general lighting

General lighting mainly focuses on human eye sensory values (color, brightness, etc). Horticultural lighting is a combination of plant growth photosynthesis and humanized environment. In addition to the brightness (lm) and light efficiency (lm/W) of basic general lighting, it also focuses on plants growth requirements include parameters such as waveband, spectral combination, photosynthetic photon radiation flux and density (PPF, PPFD), etc. Compared with general lighting, the important evaluation parameters are the number of photosynthetic quantum PPF (μmol/s) per unit time of brightness and light efficiency. PPF/W (μmol/s).


Horticultural lighting industry chain

The horticultural LED lighting industry chain involves artificial intelligence control, plant growth characteristics research, light ratio research, light source device development, and plant lighting module development. Relying on its advantages in the field of LED packaging, Refond Optoelectronics is also constantly deploying LED plant lighting packaging, module fields, etc., and can provide customized plant lighting technical solutions according to customer requirements.
